This week's From the Top from Carnegie Hall's Weill Music Room will feature, for only the second time in From the Top's history, a teenage counter-tenor. He performs two beautiful art songs with his teenage guitar-playing collaborator. Also on the program, a piece by a young composer is given its radio premiere by a quintet of From the Top alums, and a 16-year-old pianist who could give Yuja wang a run for her money performs a fiery piece by Alberto Ginastera.
